[0022] Fig. 3 is a schematic diagram showing the arrangement of the electronic component attitude changing device of the first embodiment according to the present disclosure, Fig. 4 is a schematic diagram showing a receiving section of the electronic component attitude changing device of the first embodiment according to the present disclosure, and Fig. 5 is a schematic diagram showing a state in which the electronic component attitude changing device of the first embodiment according to the present disclosure is in use. As shown in Figs. 3 to 5, the electronic component attitude changing device of the present disclosure includes a receiving section 100, an attitude changing section 200, and a supplying section 300.

[0023] The receiving section 100 includes a receiving chute 110 having an entrance end 111 and an exit end 112. The entrance end 111 of the receiving chute 110 is disposed corresponding to the visual inspection device 10. Specifically, the receiving chute 110 is disposed corresponding to one side of the turn platform 11. The receiving chute 110 can receive the electronic components 20 that have been inspected and ejected by the visual inspection device 10.

[0024] The attitude changing unit 200 has a turntable 210 that defines a rotation path 211 through its rotational movement. When placed on the turntable 210, the electronic component 20 moves along the rotation path 211 in response to the rotation of the turntable 210. The two ends of the rotation path 211 are a rotation start point 211a and a rotation end point 211d, respectively. The outlet end 112 of the receiving chute 110 is disposed corresponding to the rotation start point 211a of the rotation path 211. Specifically, the rotation start point 211a of the rotation path 211 is defined by the outlet end 112 of the receiving chute 110, and the electronic component 20 enters the turntable 210 from the rotation start point 211a. In this embodiment, the receiving chute 110 is disposed on one side of the turntable 210 along a tangential direction of the turntable 210.

[0025] The supply unit 300 includes a supply chute 310 disposed corresponding to the rotation end point 211d of the rotation path 211. Specifically, the rotation end point 211d of the rotation path 211 is defined by the supply chute 310, and the supply chute 310 is disposed on the other side of the turntable 210 along the tangential direction of the turntable 210 so as to face the receiving chute 110. The electronic component 20 that enters the turntable 210 from the rotation start point 211a moves along the rotation path 211 to the rotation end point 211d and then exits the turntable 210. The angular difference between the rotation start point 211a and the rotation end point 211d relative to the rotation center of the turntable 210 is 180 degrees.

[0026] FIG. 6 is a schematic diagram illustrating the position change of an electronic component by the electronic component position change device according to the first embodiment of the present disclosure. As shown in FIGS. 5 and 6 , an electronic component 20 is placed on a turntable 210 and moved by the turntable 210 along a rotation path 211. The rotation path 211 is a semicircular arc. The electronic component 20 has a first end 21 and a second end 22 (e.g., a front end and a rear end, but not limited thereto), and a line connecting the first end 21 and the second end 22 is defined as the longitudinal direction of the electronic component 20. In this embodiment, the electronic component 20 enters the rotation path 211 from the first end 21, but the present disclosure is not limited thereto. Depending on the needs of different manufacturing processes, the electronic component 20 may enter the rotation path 211 from the second end 22. In the rotation path 211, the electronic component 20 is arranged so that its longitudinal direction is tangent to the rotation path 211. When electronic component 20 is moved from rotation start point 211a to rotation end point 211d along rotation path 211, it rotates 180 degrees in its longitudinal direction and its position corresponds to supply chute 310, with the center of rotation of electronic component 20 in its longitudinal direction being electronic component 20 itself. In this embodiment, the rotation process of electronic component 20 is illustrated using two sequential rotation passing points (211b, 211c) of electronic component 20 located between rotation start point 211a and rotation end point 211d on rotation path 211, but the positions of electronic component 20 are not limited to these.

[0027] The supply unit 300 includes a supply wheel 320. The supply wheel 320 is disposed such that one side is located outside the rotation path 211 and the tangential direction of the one side is along the longitudinal direction of the supply chute 310. Furthermore, in the longitudinal direction of the supply chute 310, the tangential direction of the supply wheel 320 is the same direction as the rotation path 211, and the supply wheel 320 can deflect and move the electronic components 20 along the rotation path 211 to the supply chute 310. The orientation of the electronic components 20 in the receiving chute 110 and the orientation of the electronic components 20 in the supply chute 310 are different such that the first end 21 and the second end 22 are flipped 180 degrees with respect to the conveyance direction.

[0028] In the present disclosure, the method for moving the electronic components 20 to the supply chute 310 is not limited to the above-described supply wheel 320. For example, the electronic components 20 may be moved to the supply chute 310 by a blow nozzle, a push rod, or by direct dropping.

[0029] Fig. 7 is a schematic diagram showing the arrangement of an electronic component attitude changing device according to a second embodiment of the present disclosure, and Fig. 8 is a schematic diagram showing the use state of the electronic component attitude changing device according to the second embodiment of the present disclosure. As shown in Figs. 1, 7, and 8, the electronic component attitude changing device according to the second embodiment of the present disclosure is applied to a visual inspection device 10 similar to the embodiment described above.

[0030] The electronic component attitude changing device according to the present disclosure includes a receiving unit 100, an attitude changing unit 200, and a supplying unit 300.

[0031] The receiving section 100 includes a receiving chute 110 having an entrance end 111 and an exit end 112. The entrance end 111 of the receiving chute 110 is disposed corresponding to the visual inspection device 10. Specifically, the receiving chute 110 is disposed corresponding to one side of the turn platform 11. The receiving chute 110 can receive the electronic components 20 that have been inspected and ejected by the visual inspection device 10.

[0032] FIG. 9 is a schematic diagram illustrating a position change of an electronic component by an electronic component position change device according to a second embodiment of the present disclosure. As shown in FIGS. 8 and 9 , the position change unit 200 includes a mounting table 201, a turntable 210, and a chuck disk 220. A rotation path 211 is defined by the rotation of the turntable 210. In this embodiment, the mounting table 201 is fixedly disposed for mounting an electronic component 20. The chuck disk 220 is disposed on the mounting table 201, and the chuck disk is concentrically disposed on the turntable 210 so as to be rotated by the turntable 210. A plurality of receiving grooves 221 are formed on the periphery of the chuck disk 220 for interlocking the electronic component 20 with the turntable 210. The chuck disk 220 can be moved by the turntable 210 so as to rotate relative to the mounting table 201, thereby allowing the chuck disk 220 to push the electronic component 20 forward on the mounting table 201. When placed on the chuck disk 220, the electronic component 20 moves along the rotation path 211 in response to the rotation of the turntable 210. The two ends of the rotation path 211 are a rotation start point 211a and a rotation end point 211d, respectively. The outlet end 112 of the receiving chute 110 is disposed corresponding to the rotation start point 211a of the rotation path 211. Specifically, the outlet end 112 of the receiving chute 110 defines the rotation start point 211a of the rotation path 211, and the electronic component 20 enters the turntable 210 from the rotation start point 211a. In this embodiment, the receiving chute 110 is disposed on one side of the turntable 210, and the longitudinal direction of the receiving chute 110 passes through the rotation center of the turntable 210.

[0033] The supply unit 300 includes a supply chute 310 disposed corresponding to the rotation end point 211d of the rotation path 211. Specifically, the rotation end point 211d of the rotation path 211 is defined by the supply chute 310, which is disposed on the other side of the turntable 210 to face the receiving chute 110, and the longitudinal direction of the supply chute 310 passes through the rotation center of the turntable 210. The electronic component 20 that enters the turntable 210 from the rotation start point 211a moves along the rotation path 211 to the rotation end point 211d and then exits the turntable 210. The angle difference between the rotation start point 211a and the rotation end point 211d relative to the rotation center of the turntable 210 is 180 degrees.

[0034] As shown in FIGS. 8 and 9 , the electronic component 20 is placed on a turntable 210 and moved by the turntable 210 along a rotation path 211. The rotation path 211 is a semicircular arc. The electronic component 20 has a first end 21 and a second end 22 defined therein, and a line connecting the first end 21 and the second end 22 is defined as the longitudinal direction of the electronic component 20. In this embodiment, the electronic component 20 enters the rotation path 211 from the first end 21, but the present disclosure is not limited thereto. Depending on the needs of different manufacturing processes, the electronic component 20 may enter the rotation path 211 from the second end 22. In the rotation path 211, the electronic component 20 is arranged such that its longitudinal direction is tangent to the rotation path 211. When electronic component 20 is moved from rotation start point 211a to rotation end point 211d along rotation path 211, its longitudinal direction rotates 180 degrees and its position corresponds to supply chute 310, and the longitudinal direction of electronic component 20 rotates around the same center as turntable 210. In this embodiment, the rotation process of electronic component 20 is illustrated using two sequential rotation passing points (211b, 211c) of electronic component 20 located between rotation start point 211a and rotation end point 211d on rotation path 211, but the positions of electronic component 20 are not limited to these.

[0035] In this embodiment, the supply unit 300 may have a blowing nozzle 330 arranged to blow gas into the supply chute 310 along the longitudinal direction of the supply chute 310. In this case, the electronic components 20 in the storage grooves 221 can be blown into the supply chute 310 by the blowing nozzle 330. The orientation of the electronic components 20 in the receiving chute 110 and the orientation of the electronic components 20 in the supply chute 310 are different from each other such that the first end 21 and the second end 22 are inverted 180 degrees with respect to the conveyance direction. Furthermore, sensors (not shown) for detecting whether the electronic components 20 have reached predetermined positions may be selectively arranged at each of the rotation start point 211a and the rotation end point 211d, and the operation of the turntable 210 and the blowing nozzle 330 may be controlled by a controller (not shown) based on the detection results.

[0036] In the present disclosure, the method for moving the electronic components 20 in the accommodation grooves 221 to the supply chute 310 is not limited to the above-described blow-out nozzle 330. For example, the electronic components 20 may be moved to the supply chute 310 by a push rod, direct dropping, or other methods.

[0037] The outlet end 112 of the receiving chute 110 is disposed adjacent to one side of the chuck disk 220, and the supply chute 310 is disposed adjacent to the other side of the chuck disk 220. Each storage groove 221 has an opening disposed outward along the radial direction of the turntable 210. However, the present disclosure is not limited thereto. Any one of the storage grooves 221 can reach the outlet end 112 of the receiving chute 110 and the supply chute 310 by the chuck disk 220 rotating concentrically following the turntable 210. In this embodiment, the electronic component 20 rotated by the turntable 210 advances along its short-side direction (i.e., a direction passing through the electronic component 20 itself and perpendicular to the long-side direction). Therefore, even if the electronic component 20 is displaced relative to the turntable 210 during transfer, such displacement typically occurs in the short-side direction of the electronic component 20. According to this embodiment, the chuck disk 220 can prevent the electronic component 20 from moving in the short-side direction and becoming unable to be aligned with the supply chute 310.

[0038] 10 is a schematic diagram showing a reversing guide rail of an electronic component orientation changing device according to the present disclosure. As shown in FIGS. 1, 2, and 10, the electronic component orientation changing device according to the present disclosure is applied to a visual inspection device 10 similar to the embodiment described above.

[0039] The electronic component attitude changing device according to the present disclosure includes a receiving unit 100, an attitude changing unit 200, and a supplying unit 300.

[0040] The receiving section 100 includes a receiving chute 110 having an entrance end 111 and an exit end 112. The entrance end 111 of the receiving chute 110 is disposed corresponding to the visual inspection device 10. Specifically, the receiving chute 110 is disposed corresponding to one side of the turn platform 11. The receiving chute 110 can receive the electronic components 20 that have been inspected and ejected by the visual inspection device 10.

[0041] This embodiment differs from the previously described embodiments in that the attitude changing unit 200 includes a reversing guide rail 230. The reversing guide rail 230 includes a spiral chute 231 connected in series with the receiving chute 110. The spiral chute 231 extends along the longitudinal direction of the reversing guide rail 230 and has a twist angle of 180 degrees.

[0042] 11 is a schematic diagram showing the position change of an electronic component by the electronic component position change device according to the present disclosure. As shown in FIGS. 10 and 11, the spiral chute 231 has a reverse start point 231a and a reverse end point 231g. The electronic component 20 is fed into the spiral chute 231 from the reverse start point 231a and transported along the spiral chute 231 to the reverse end point 231g. In this embodiment, the spiral center axis of the spiral chute 231 is located within the spiral chute 231. Specifically, the reverse start point 231a and the reverse end point 231g are defined to be at both ends of the spiral chute 231. The spiral center axis along the spiral chute 231 is defined by the movement direction of the electronic component 20 as it passes through the spiral chute 231. The reverse start point 231a is located upstream of the reverse end point 231g in the movement direction of the electronic component 20 as it passes through the spiral chute 231. In this embodiment, the inversion process of electronic component 20 is illustrated using several inversion passing points (231b, 231c, 231d, 231e, 231f) that electronic component 20 passes through sequentially as it moves from inversion start point 231a to inversion end point 231g, but the position of electronic component 20 is not limited to these. Electronic component 20 is defined with a first side surface 23 and a second side surface 24 (for example, but not limited to, the front and back surfaces, the back and front surfaces, or the left and right sides) facing first side surface 23. As electronic component 20 moves from inversion start point 231a along spiral chute 231 to inversion end point 231g, electronic component 20 is pushed forward and rotates around its moving direction as a central axis. The orientation of electronic component 20 at inversion start point 231a and the orientation of electronic component 20 at inversion end point 231g are different such that first side surface 23 and second side surface 24 are flipped 180 degrees.

[0043] A longitudinal opening 232 communicating with the receiving chute 110 is provided on one side of the reversing guide rail 230. The longitudinal opening 232 is for inserting a push rod for pushing the electronic component 20 forward, if necessary.

[0044] In this embodiment, the first end 21 and the second end 22 of the electronic component 20 may be turned over by the turntable 210 described in the first or second embodiment before being turned over by the turning guide rail 230.

[0045] As described above, in the electronic component inspection device according to the present invention, the posture changing unit 200 can change the posture of the electronic component 20 by the turntable 210 and the reversing guide rail 230 to a posture suitable for the subsequent work.

[0046] The above is merely a preferred embodiment of the present invention, and does not limit the scope of the claims of the present application. Other equivalent modifications utilizing the spirit of the present invention are intended to be included in the scope of the claims of the present application. [Explanation of symbols]
